I comm: 1 Be it known that I, Timon-mus Kennucrnn, a. citizen of the United States, residmg at Saut Paula, in the county of Venturn and State of California, have invented new and useful Improvements in Revolving Pistons, of which the following is aspecification.

This inz'cntion relates to piston constructions and has for its object to provide a g-istonso connected to its 'pitmanthat the piston is adopted to rotate about'its own A further object of the invention is to object to "with provide means for itively im lling a rotative motion to t eiston an it is an rovide im g means acting antomigtic during pitman durinl rotation of a crank I which t bined mf embodiment ofthe s nse is describeddn the following specification and illustrated in the aceompenying drawings,

.in which Fig. 1 is a longitudinal section of e chemher in which a xston reciprocates, and with \which the rotating means is combined. Fig. 2 is a longitudinal section taken on at right angles to the plane of Fig. 1.

The invention 18 embo led'in the resent case in combination with aninterna combustionen "no-cylinder 2 in which there is reciprocal: with a head 4;, having. mall arranged, a ball seat or socket 5 which may be formed within an axial boss 6. The boss is shown as externally threaded to receive the inter- '9 and throughthis extends a; thread n'ally threads flange -8 of a ball cup or socket 7 com lementary to the ball seat 5.

The socket member-7 has a central'a rture shank or stem IOattached to, or forming a part of, the contiguous end of e connecting rod or pitma'n 11 -whose swinging end is connected to the engine crank 12. c

On the outer end of the threaded stem 10 is rovided a ball 13 clamped between the bail seat 5 and the socket member 7 and therefore, providing a universal or ball joint. This permits of rotation of thepi s Application flied my 5, 1922. Seth! H0. 558,583

t is desirable to provide means for 'positively im 'arting a. rotary motion to the piston an means for that purpose are provided herewith. A form of impellmgdcrice is indicated as comprising one or more,

What isol aimed is:

2. A reciprocating piston and e pitman rod operativelp connected thereto to reciprocate the piston, a. ball and socket connection between the piston and the itman providing for complete rotation of e piston on its own axis, and means for positively y roviding a plurality of V ilFbeseen-that while one o e by virtn' for arron in impertingafull roterymotion to thepiston during its reeiproc'etxons.
